BUNG FIXTURE FOR BARRELS Filed May 21, 1928 2 SheetsSheet 2 MW W NVENTOR Patented Apr. 28, 1931 UNITED STATES PATENT OFFICE THEODORE W. RIEKE, OF AUBURN, INDIANA, ASSIGNOR T RI'EKE METAL PRODUCTS CORPORATION, A CORPORATION OF INDIANA BU'NG FIXTURE FOR BARRELS Application filed May 21, 1928. Serial No. 279,448.

This invention relates to improvements in bung fixtures for barrels, and the object thereof is to provide in connection with the bung opening fixture of a metallic barrel, a means for securing a sealing device applicable to the bung by which the bung opening is closed, whereby unauthorized removal of the bung from the bung opening will be detectable. Another object of the invention is to apply a securing means for a seal inconnection with the head of a'metallic barrel about the bung opening therein in such manner, and of such construction, that manufacture thereof will be facilitated and economical.

These objects are accomplished by the. construction illustrated in the accompanying drawings, in which I Fig/1 is a plan view of a bung fixture and 'bun g embodying the invention applied to the head of a metallic barrel, portions thereof being broken away;

Fig. 2 is a transverse section'of Fig. l on line 2--2 thereof;

Fig. 6 is an elevation projected frowrbn Fig. 5

Fig. 7 is an elevation of the em ossment made in the head sheet, the bung ring and seal ring being shown applied thereto as they appear in a preliminary stage in the manufacture of the bung fixture,the head sheet being shown in sect-ion; v

Fig. 8 is a similar view showing the same in a succeeding stage of manufacture; and

Fig. 9 is also a similar view of the fixture in its completed stage.

The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding char acters.

' The seal ring 1 is formed of thin sheet metal and is first formed with an upstanding annular flange 2 at its inner margin, and with a series of perforated ears 3 extending radially outward from its outer margin.

The seal ring is applicable to that type of bung fixture in which a bung ring 4: is secured in a circular envelope 5 that is formed in the metallic wall or head sheet 6 of a barrel similar to that shown in my previous invention, patented December 6, 1927, No. 1,651,632, for fittings for containers.

In the present instance the bung ring is the embossment.

and the adjacent wall of the embossment becomes inset beneath the flange of the bung ring, as shown in Fig. 8. The embossment and the seal ring flange are then crushed downwardly toward the top surface of the sheet 6 by means of suitable die mechanism (not shown). Resulting from the latter operation the flange 2 of the seal ring becomes clamped betweenthe overhanging outer margin of the embossment 9 and partakes of the escalloped formation of said embossment whereby the seal ring is fixedly secured and turning movement thereof upon said embossment is prevented.

Also, the crushing operation clinches the flange of the bung ring within the embossment so that the flange of said bung ring is enveloped thereby and is held from turning therein by the interlocking relation of the scallops on the flange of the bung ringwith those formed in the'embossment.

The bung opening is closed by a bung of ordinary construction and is provided with an opening 11 in its flange adjacent the outer perimeter thereof, the bung having 5 threaded relation with the bung ring 4, there being'a gasket 12 that is clamped by the flange 13 of the bung against the top face of the embossment 9 so that the bung opening is sealed thereby.

One of the ears 3 is bent upwardly and a seal-wire 14 is laced through the perforation in the ear and the opening 11 in the flange of the bung, and'the ends of the seal-wire are secured by applying an ordinary seal 15 from the bung opening in the barrel, without breaking the seal-wire or mutilating the ear of the seal ring is prevented.

A feature of the invention is that the seal ring is permanently and fixedly clinched into connection with the embossment formed of the metallic sheet of the barrel, whereby it is immovable in relation therewith.

What Iclaim is I 1. A bung fitting for a container formed of sheet metal and having an opening therein, a circular embossment formed in the sheet surrounding said opening and concentric v therewith, the wall of said embossment adja- 30 cent its top being escalloped; a hung ring having an external flange at one 'end, the

- outer periphery of said flange being escal loped and having interlocking relationwith the escalloped wall of said embossment when said ring is in place; a seal ring having an internal flange encompassing said embossment, and fixedly secured thereto when the embossment is clinched upon the flange of said bung ring; and a-bung threaded in said bung ring and having closing relation with said opening, there being perforations in said bung and seal ring for the reception of a seal whereby turning movement of the bung is prevented.

2. A bung-fitting for a container formed of sheet metal and having an opening therein, a circular embossment formed in the sheet surrounding said opening, the wall of said embossment adjacent its top being. escal- 5 ]oped;'a bung ring having an external flange at one end shaped to fit into and have interlocking relation with said embossment,,the wall of said embossment being clinched upon said flange so as to overhang the adjacent .55 face of the sheet of whichthe container is formed; a seal ring having an internal flange around its inner margin, which is secured about the embossment by the overhanging wall thereof, the flange ofsaid seal ring being.

80 conformed to the escalloped wall; and a bung threaded in said bung ring' and having closing' relation with said opening, the head of said bung and said sealring having perforations for thereception of a seal.

3. A bung fitting for a container formedthereto. In this manner removal of the bung of sheet metal and having an opening there- III, a circular embossment formed in the mewith an irregular or escalloped outer periphery; a bung ring having an external flange enveloped by and having interlocking relation with said embossment; a seal-ring encompassing said embossment. its inner portion having a flange that is clinched in place between the overhanging wall of said embossment and the face of the sheet of which the container is formed; and a. bung threaded in said bung ring and having closing relation withsaid' opening, said bung and seal ring being so formed as to have applied thereto a seal whereby the bung is prevented from being turned.

4. An appliance for securing a sealing means to a bung as applied to a container formed of sheet metal, in combination with the embossment in which the flange of the bung ring for the container is enveloped, a seal ring having outwardly extending perforated ears, the inner margin of said ring encompassing said embossment and being provided with a flange that is clinched in fixed position between the outer wall of said embossment and the adjacent face of the sheet of which the container is formed.

5. A bung fitting for a sheet metal container having an opening therein, an envelope formed in the wall of the container about said opening, which envelope overhangs that por tion of said wall adjacent thereto; a bung ring having an external flange that is immovably secured in said envelope; and a seal anchor clinched in fixed connection with the container between the overhanging envelope and adjacentface of said wall.

In testimony whereof I aflix my THEODORE W. R

si nature.
